Which statement is best explained by the model?
A cell wall is found only in plant cells and a cell membrane is found only in animal cells.
Larger cells have larger cell membranes, so they are more efficient at moving materials in and out of cells.
Match the cell organelle to its function.

Which statement is best explained by the model?
Mark is making a model of a living plant cell. The following objects are available to Mark for his model:
- a cloth bag
- a wire cage
- a solar panel
- a battery with wires
- a zippered sandwich bag (Ziploc)
Mark wants to represent the function of different plant cell parts by using objects that have functions similar to the cell’s parts.
Using a complete sentence, identify three of the above objects Mark can use in his model and describe what part of a plant cell they would represent AND WHY.
